As more details come out regarding the Iran nuclear deal taking shape ahead of a March 31 deadline, Transportation Minister Yisrael Katz (Likud) on Tuesday called on Labor head Yitzhak Herzog to join Prime Minister Binyamin Netanyahu in his March 3 Congress address to warn against a bad deal.

On Monday some progress was reported in talks, with diplomats admitting Western powers aim for a deal lasting at least ten years under which Iran will be left with its centrifuges, but would need at least one year to produce enough highly enriched uranium for a single nuclear bomb, the so-called "breakout" capacity. Iran has been pressing for 19 times its current enrichment capacity.

"Now it's clear - Netanyahu was right," said Katz. "The nuclear deal coming together with Iran is a serious threat to the security of Israel."

Amid calls by former leading Democratic Senator Joseph Lieberman on Democrats to listen to Netanyahu's warning in Congress, Katz added "more and more sources in the US, including senior members of the Democratic party, understand and are lining up with the prime minister."

"The trip to the US is the last opportunity to prevent a bad deal. I invite the chairman of the Opposition Buji (Yitzhak) Herzog - leave (Tzipi) Livni at home and join the prime minister's visit. Present a consensus and a unified stand and help get rid of the danger," called Katz, in a jab at Herzog's joint "Zionist camp" with Livni's Hatnua.

It remains likely inevitable that Herzog will not join Netanyahu given his incessant criticism of the trip, claiming that the invitation by Republicans without White House approval in advance harms relations between Israel and America.

Herzog previously said that in going to Congress to warn about the Iranian nuclear threat, Netanyahu decided to "throw Israel's security under the elections bus."

He also claimed "this speech that was born in sin as an elections production endangers the security of Israeli citizens and the special relations between Israel and the United States."

After the US admitted to hiding details about the Iran negotiations from Israel, Netanyahu responded to the administration of US President Barack Obama, saying if the deal is safe "what is there to hide here?"

Iran just this Saturday threatened Israel, saying it can destroy Tel Aviv within ten minutes with the rockets in its possessions, heightening fears about leaving the Islamic regime with nuclear capabilities.
